[jira] [Comment Edited] (HBASE-2315) BookKeeper for write-ahead
logging
[ https://issues.apache.org/jira/browse/HBASE-2315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13399220#comment-13399220 ]

----------------------------------------------------------------
Here is the JIRA that tracks parallel hdfs writes:
HBASE-6116 Allow parallel HDFS writes for HLogs
HBASE-5699 would allow multiple WALs per region server. Grouping of edits can be per-table or, one WAL per region.
WAL interface abstraction appears in the discussion there.
Feel free to propose WAL interface for this JIRA.

> BookKeeper, a contrib of the ZooKeeper project, is a fault tolerant and high throughput write-ahead logging service. This issue provides an implementation of write-ahead logging for hbase using BookKeeper. Apart from expected throughput improvements, BookKeeper also has stronger durability guarantees compared to the implementation currently used by hbase.
